imx8mn eMMC boot partition

Hi,

Does anyone have an idea where to find the definition of the offset used when booting from eMMCs boot partition?

I tried to write the flash.bin image to offset 32k (page 0x40) into the boot partition of the eMMC and seledted the bootpartition with "mmc partconfig 2 0 1 0". The board did not start. After writing the flash.bin to offset 0 the board starts.

When writing to microSD the offset 32k is ok.

I' using an NXP imx8mn evk board.
